This patch adds the paths for searching for instance allocators and
makes the LUTestAllocator code run the allocator and return the results
if the direction specified is 'out'. 'out' means that the opcode will
return the result of the allocator run, instead of the allocator input
file ('in').

The patch unifies all names to refer to 'iallocator' instead of plain
allocator.

The patch also adds an example allocator that can be used for testing
this new functionality.

Having the individual parts in the code allows us to build version
numbers like "1.2" while leaving "3" out in a clean fashion, that is
without regular expressions or the like. This might be used together
with configuration format versions.

Why m4 code? AM_INIT_AUTOMAKE, which could take a shell variable, is
considered deprecated[1] and should be replaced by AC_INIT. Unfortunately,
AC_INIT is expanded at build time, so one has to use m4 to build
composite values like this version number[2].

number, as there are no other changes. We'll update the web site to
indicate that the current install.html document is valid for 1.2.3 too.
